NEC uPD9245GJ Super Resolution ASSP

NEC’s uPD9245GJ system on a chip (SoC) increases resolution and image quality when low-resolution video and still images are displayed in high-resolution. The new application-specific standard product (ASSP) is based on NEC’s single-frame super-resolution technology. The uPD9245GJ reduces the blurring that occurs when low-resolution images are expanded and displayed in high-resolution. The ASSP sharpens out-of-focus images, smoothes rough edges and refines contours by analyzing and processing information contained in one frame of data in real time. Using standard video interfaces for data input and output, designers can easily integrate the ASSP into a wide variety of consumer, industrial, medical, and automotive devices that handle images and video. Samples of NEC’s uPD9245GJ ASSP are available now with pricing beginning under US$10 for more than 1,000 pieces and US$30 in lower volumes. Super-resolution IP cores are also available for NEC’s cell-based ASIC (CB-90 and CB-12) and gate array (CMOS-12M) libraries.

NEC Electronics’ super-resolution technology enables very high-resolution processing with just one frame of image data. Reducing the processing load eliminates the need for expensive, external high-capacity memory, such as double-data-rate (DDR) SDRAM, thereby reducing cost and power consumption, and simplifying connections to existing systems. With standard video interfaces such as 24-bit CMOS I/O with RGB or YUV for easy connection, the super-resolution ASSP easily can be added to existing designs.

The technology enhances image data from quarter video graphics array (QVGA) resolution (320 x 240 pixels) to wide VGA (WVGA) resolution (800 x 480 pixels) for clear image display on mobile phones and car navigation systems. The technology also achieves crisp images in 1920 x 1080-pixel high-definition (HD) television broadcasts by boosting image data in the 640 x 480-pixel VGA format ordinarily used for TV broadcasts and DVD storage to 6x the resolution.
